Answer: That's a difficult question to answer. To begin with, there's an ecosystem within your deck garden. Large insects feed upon small insects, and tiny insects help in the decomposition of organic matter. Healthy soil depends upon insect activity, and many insects pollinate flowers. If you used a fogger, you'd kill the nuisance pests along with the beneficial insects. How about targeting the real pests, rather than eliminating all insects? If, for instance, aphids are feeding on your roses, you can direct a spray of plain water at them to wash them off your plant. If wasps are a problem, you can make a trap out of a mason jar and a funnel, put a piece of meat or fish inside the jar, place the funnel in the top, and set the trap away from your picnic table. When your picnic is over, or when you're ready to go inside, just take the funnel out of the jar. The wasps will fly away, with no harm done to you or your picnic. Hope you'll consider these options instead of using a chemical to eradicate all the insects in your garden.
